Over the past several decades, there has been a host of research conducted to improve rehabilitation and enable assistive technology for persons with disabilities (e.g., cognitive, physical) through augmented and virtual realities. However, the technology driving this area needs to advance towards the state-of-the-art. We believe this situation could be improved if the two contributing communities to this area - the technology and the clinical communities - had greater opportunity for more direct interaction and collaboration to advance the field. This demonstrated need for collaboration and discussion between these two communities is the primary purpose of this workshop. Specifically, we are inviting submissions of position papers and preliminary research that focus on 1) novel Virtual and Augmented Reality technologies that could be used to enhance assistive technologies, although they may not have been used for this yet and 2) insights into and studies involving persons with disabilities and the impact of VR, AR, and associated technologies.
